It is a mistake to lose courage because your apponents score the first three or four goals.
Do not begin to play roughly because you are losing; and do not purposely and ostentatiously avoid scoring against a team that has already lost, because even if a bad beating does discourage them they would rather suffer it than be humiliated by any such show of pity.
Do not imagine that after winning a few games the match is won, because "accidents" occur, and do not dream of laurel wreaths and championships on account of your success in the opening of the series.
Attend every practice but do not become over trained.
A man should not lose his temper because he suffers a sore knock. A display of "fireworks" is often the cause of an undesirable rest among the spectators.
Do not question the decision of the umpire or referee. Let your captain plead the case.
